Key Fob Repair Service

Key fobs take a beating. Depending on how they're stored and how often they're jostled, their buttons can get stuck or damaged.

Most key fob issues are fixable. However, there are some that are more complicated and require expert assistance. A locksmith can be of great help in these cases.

Dead Fob Battery

Car key fobs have become quite intelligent, but that doesn't mean they don't occasionally find themselves in the "not responding" zone. It's time to replace your battery if this happens. This won't fix the issue since there may be an issue with one of the terminals on the battery connector.

The car makers are aware of the potential problem, and they often install an extra mechanical key in the fob for use in an emergency. To gain access to this, locate the small release switch or latch on the back of the fob (check the user's manual for specifics). Pressing this button, you can open the fob and reveal a key that you can use to unlock the car.

Another indication that your fob's battery is dying is that you have to be much closer to the car to unlock and open it than you did before. This is because the fob's transmitter weakens as its battery ages and limits its operating range.

It is relatively easy to replace the battery. You'll need to purchase a button-cell battery (which looks like the size of a small silver coin) and then follow the steps in the user manual to take out the old battery. Then, replace the new battery in the same way that the old one was placed (the positive side should face upwards towards the buttons). Test the lock/unlock function, and start the functions of your fob after reassembling it to ensure the new battery is placed correctly.

You can open some key fobs by looking for the latch, screw, or switch in the back and then prying the fob in two. Be careful not to break the fob because you'll need it to connect to your vehicle! You could also take the key fob to an expert in case you're not comfortable doing it yourself. Since it's a common service, most auto shops will replace the battery inside a fob for a nominal fee. Some dealers may even do it for free dependent on the make and model of your vehicle.

Fob Is Not Working

The first thing you need to do in the event that your key fob doesn't seem to be working is to replace the batteries. This is the quickest fix and will most likely fix the issue. If your fob still does not work after changing the battery it could be caused by damage.

Damage can occur to your car key fob for a variety of reasons including physical trauma, water exposure or a damaged circuit board. These issues can stop your key from sending the signal to the receiver in your vehicle, which could stop your car's ignition or doors from locking. If your fob is damaged, it's likely that you'll need a professional to replace the component or the entire device.

The buttons on your fob might have worn out due to repeated use. The rubber may wear out making the buttons less 'clicky' or springy. They may also stop registering your press. You can try wiping down the buttons and adjusting them to see if that fixes the problem However, it's generally recommended to send the fob to have it professionally evaluated for more thorough repairs.

Double check that the battery you're using is the right one for your fob. You can find a list online or in a majority of hardware stores. Refer to the owner's guide or the engraving on your fob for further details. If the battery is not the correct fit it could have problems transmitting strong signals and providing enough power to internal components.

In rare instances it could be a problem in the vehicle's electronic parts or receiver. If you have an inductive backup system, you can test it by opening the doors with a physical key and then beginning the car using the inductive backup (if available). If the physical key you have not open or start your car, you should have a mechanic inspect the receiver and electronic components to make sure they're working correctly.


Fob that is damaged

A key fob contains numerous components that function together and a single malfunction can cause other parts to fail. If a keyfob stops working, it's important that you check for obvious causes like cracks in the casing or a damaged component. Check the horn, lights and other parts of the car to ensure that they are functioning properly.

It is better to replace the key fob if it's damaged, rather than try to repair it. The fob could require reprogramming to the vehicle this is something that cannot be done at home and requires specialized equipment to do so.

Over time the contacts on buttons of a key fob can wear out. This is most common when the fob is dropped or left in hot temperatures.

Over time the internal wiring of the key fob could wear down. This can result in a button not working when it's pressed or only working when it's press very hard. It could also result in the car not being able to start or unlock when the fob is used.

Most fobs have the cover of plastic which can be loosened and cleaned using soap and water. This is often able to restore a key fob to functioning properly and it's a good practice to clean it regularly to prevent dirt from damaging the insides.

A bad battery is the most common reason why the key fob will not turn on or work. Many mechanics and car dealers are able to replace the batteries in a short time but if you're at ease doing it yourself you can purchase a new battery at the hardware store or a big-box retailer and follow the instructions in your owner's manual or on YouTube to install it.

The worst-case scenario is that the key fob has internal damage, for example cracks in the case, tiny electronic components that aren't fully attached to the circuit board, or bent or corroded battery contact points. If you find any of these issues, you should consult an auto locksmith or dealer to obtain a new key fob and help in programming it for your vehicle.

Fob isn't programming.

The car key fob is a convenient way to start your engine and open the doors of your car. They can also cause frustration when they stop working or appear to be working intermittently. In some cases the issue could be as simple as replacing the battery, but in other cases it could require an even more complex repair. The first step is to identify the reason for the fob not functioning correctly.

One of the most frequent causes of a malfunctioning fob is that it has stopped recognizing your vehicle. This is because the connection between the remote and your car is interrupted. This connection can be reset without the need for an expensive key fob repair .

When the key fob is not sending a clear signal, other problems can occur. This can happen if the key is damaged or the battery is not functioning properly. In either case, you should try to resync your key with your car. This can be accomplished by following the directions on the key fob. It's also a good idea to carry a spare key with you to make use of it in the event that the primary key isn't working.

It's possible that the fob doesn't receive the signal sufficiently strong from the car. This could be due to a weak car battery or interference from wireless devices, or an antenna issue. By using a remote tester you can test the fob to check if it's the cause of the issue. If the tester doesn't illuminate when one of the buttons is pressing, the battery may need to be replaced or the fob could be broken.

Another reason that a fob not sending the right signal is that the car's immobilizer system is preventing it from doing so. This could be the case in the event that your key fob isn't been programmed correctly, or if you have a software issue.

If you can't fix the fob or it isn't worth the effort to fix it, you should purchase an entirely new one. Many online retailers offer low-cost options, and some can be delivered to your residence.
